Antioxidant capacity of temulawak drink (Curcuma xanthorrhiza) with white crystal sugar cane, red crystal sugar cane, palm sugar, and arenga palm sugar

Rum SSN, Kawiji, Setyaningrum A. 2016. Antioxidant capacity of temulawak drink (Curcuma xanthorrhiza) with white crystal sugar cane, red crystal sugar cane, palm sugar, and arenga palm sugar. Biofarmasi 14: 39-46. The aim of this study was to determine the antioxidant capacity of temulawak extract in water solution; to determine the antioxidant capacity of white crystal sugar cane, red crystal sugar cane, palm sugar, and arenga palm sugar which commonly used in making temulawak drink; to determine the synergic effect of sugar addition to temulawak drink product; and also to determine the sensory quality (colour, taste, and flavour) of temulawak drink produced by parameters. This research used Completely Randomized Design (CAD) with two factors, concentration of temulawak extract (10, 20, and 30 gr/litre), and the kind of sugar added (white crystal sugar cane, red crystal sugar cane, palm sugar, and arenga palm sugar) with 50 g/litre concentration of addition, respectively. This research was studied the antioxidant activity (radical DPPH scavenging activity), total phenol, and sensory analysis (Multiple Comparison Test). Statistical analysis was performed using SPSS 17.0 (α=0,05). This study showed that the radical DPPH scavenging activity and total phenol were increase due to the increase of temulawak extract concentration. It might be due to water-soluble phenol compound like xanthorrizol extracted more largely. Radical DPPH scavenging activity and total phenol of sugars were significantly different which from the highest to the lowest palm sugar, arenga palm sugar (which usually used by people to make traditional health drink), red crystal sugar cane and white crystal sugarcane, respectively. Synergic effect of temulawak drink antioxidant capacity occured due to the sugar addition. The study also showed that sensory quality of produced temulawak drink with all treatments was not significantly different.
